SPECIFICATION forming' part of Letters Patent No. 612,140, dated October11, 1898.

Application filed March 3, 1898.

To all whom it may concern:

Be it known that I, JOSEPH RILING, a citizen of the United States,residing at Philadelphia, county of Philadelphia, and State ofPennsylvania, have invented'a new and useful Improvement inGlass-Presses, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, whichform a part of this specification.

My invention has for its object to construct an apparatus for thecasting ofglass' articles which by the manipulation of a singlecontrolling device by the operator will bring a plurality of moldssuccessively under the plunger-die, operate the plunger-die toform theglass articles, and successively withdraw the articles so formed frombeneath the plunger-die and convey them to the annealingoven. i

The invention consists in a plunger-die and mechanism for reciprocatingthe'same, combined with a traveling conveying apparatus divided intosections, each section carrying a mold or female die, the severalsections being adapted to be brought directly succes sively under themale die and follower, and thence to travel forward and by successiveupsetting actions of the several sections eject the molded glassarticle.

In the drawings, Figure l is a front view. Fig. 2 is a partial rearelevation. Fig. 3 is a sectional View on the line 3 3, Fig. 2. Fig. 4 isa sectional view on the line 4 4 of Fig. 3. Fig. 5 is an invertedperspective of the cam for operating the locking-lever. Fig. 6 is adetail plan view of the shifting and locking mechanism. Fig. 7 is a sideelevation of the same. 7

I will first describe briefly the press mechanism for actuating theplunger-die A and follower B.

U is the frame of the machine.

A is the plunger, carrying the die a and the follower B. The'rods h I)extend through orifices in the follower-plate B, so that thefollower-plate B is' secured upon said rods by the nuts Z) I) on thelower end of said rods. The plunger is secured to the cross-head A, andbetween the follower-plate B and crosshead A and surrounding the rodsh bare Serial No. 672,353. (No model.)

strong spiral springs b b The rods 12 b extend beyond the cross-head A,through the fixed guides A A and are connected together by thecross-head A Secured to the frame of the machine is the frame E,supporting the shaft 6, to which is secured the counterbalance-rod E,one end of which has the hook e" engaging the crosshead A, and has uponthe other the counterbalance-weight E F is a cylinder having thepiston-rod F connected to the cross-head A and the piston. (Not shown.)

G is a valve-chamber having a piston connected to the rod 9 g is aninlet to the valve-chamber from an air-compressor. (Not shown.)

glis an exhaust-passage from the valvechamber. The rod is connected to alever g which is connected to a foot-treadle (not shown) by means of thelink-g The valve-chamber and piston-chamber are suitably connected byair-passages, so that the reciprocation of the valve-piston causes acorresponding reciprocation of the piston that is, when the operatorforces down the treadle the valve is operated to admit air above thepiston, and when his foot is removed it returns the valve to itsoriginal position, admitting air beneath the piston. I have not shownthese air-passages, as they constitute no part of my invention.

When the treadle is depressed to admit air above the piston, the pistonmoves downward, forcing the cross-head A, and with it the plunger A,and, through the springs 19 b the follower B. The follower reaches itsultimate position before the plunger strikes the glass in one of thedies 0. The dies 0 are brought successively beneath the plunger andsupported rigidly in that position in a manner to be hereinafterparticularly described. The further movement of the piston moves theplunger A farther downward, holding the follower fixed by thespring-pressure. The

downward movement of the plunger continuesuntil it has squeezed themolten glass out to fill the combined mold, and when this occurs thepiston ceases its downward movement. \Vhen the operator releases thetreadle, the valve is reversed, thus admitting air oted to thehorizontal rod- N and held againstbeneath the piston This lifts thepiston and, through the medium of rodsb b, the pl unger and follower.The counterweight E accelerates this upward movement.

I provide the following mechanism for carrying and supporting theseveral female dies:

K K are two octagonal-shaped sprocketwheels or pulleys mounted on theshafts 7s the shafts being supported in bearings, so as to be freelyrevoluble. Around said sprocketwheels extends an endless chain composedof the hinged sections L L, each section being of a size correspondingto one of the flat surfaces of wheels K K. These sections consist ofblocks, and each block sustains a mold O,

which is bolted to the section by means ofbolts 0'. The blocks arehinged or pivoted together by means of hinges 0 They are shown in planin Fig. 4.

I provide the following mechanism for turning the wheel K so that thesections may be brought successively under the plunger and held thereuntil the pressing or molding operation is completed:

M is a ratchet-wheel on the shaft 70. This ratchet-wheel has detentsequal in number to the fiat surfaces on the wheel K. This ratchet-wheelis operated by the pawl m, pivthe ratchet-wheel by means of gravity.This rod N is adapted to slide in bearings n on the Each section L hasan inset or notch Z in one end. Secured to the frame of the ma chine isa bell-crank lever one arm 0 of which normally presses against the endof the adjacent section under the tension of a spring 0 and fits andengages the inset Z when the section is moved forward, being pressedtherein by the spring 0 and thereby locks the section engaged frommoving. The other arm 0 of the bell-crank lever is in alinement with acam P, carried by rod N. By the engagement of this cam with arm 0 arm 0is withdrawn from engagement with the section, so as to permit thesection to advance, as I will now proceed to more fully describe.

Secured to the rod N so as to surround the same is the block P, to theunder side of which is pivoted the cam P, the block and cam being shownin inverted perspective in Fig. 5. The under side of this cam has aninclined facep, thinnest at its free end. The free end of the cam iswidened out, so that the edge of the cam nearest the section L presentsan inclined face 19. A leaf-spring P normally holds the cam P in theposition shown, in which position it is in alinement with the cam O ofthe bell-crank.

As the sections move from left to right the arm 0 is held against theadjacent section'by the tension of leaf-spring O and drops into theinset in the section, as before described,

frame of the machine. Secured to the rod N is the sliding block 12 n isa link connected to the sliding block 12 when the section has advanced asufficient distance to bring its inset immediately opposite arm O, whichoccurs when the rod N has and the other shaft n, which rests in ahearing on the frame E, is supported on the frame of the machine.Connected to the other end of the rock-shaft is the crank M, which inturn is connected at its opposite end to the link a which link isconnected to the arm a", secured to the cross-head A".

As the cross-head A is depressed in the downward movement of theplunger-die the rod N is caused by the mechanism just described to slidefrom right to left, and the pawl m slides from the position illustratedover the long face of one of the detents until it drops into position toengage the next succeeding tooth. As the cross-head A is elevated 1n theupward movement of the plunger-die the rod N .is drawn from left toright, the pawl 'm engages one of the detents in the ratchet-Wheel M,and the wheel K is given a one-eighth revolution, causing the entireseries of sections to move forward such a distance that the nextsucceeding section is brought beneath the plunger-die.

It is necessary that the sections be advanced precisely the samedistance each time and that the female dies carried thereby be stoppedand held successively in such position beneath the plunger-die that thetwo dies will be.

in exact alinement. In order, therefore, to maintain accuratepresentation of the female die to the reciprocating plunger-die duringthe downward movement of the press, I have provided the followingmechanism:

reached its extreme limit of movement to the right. During the movementof the rod from right to left it is necessary that the engagement of thearm 0 with the section should be maintained, for during this movement ofthe rod the pressing operation takes place. Just before the rod reachesits extreme limit of movement to the left the inclined face 19 of thecam P engages the end of arm 0 but as the engagement is an end' thrustthe bellcrank does not swing,but the cam itself swings outwardly on itspivot against the action of the spring P returning immediately to itsnormal position as soon as the cam passes beyond the arm 0, which occursjust before rod N has been shifted to its extreme position to the left.When the upward movement of the plunger begins, the rod starts to shiftfrom its extreme left position. The sections, however, do not begin toimmediately move, as the pawl has passed in its movement from right toleft some distance beyond the next succeeding tooth of the ratchet.Before the pawl engages the ratchet the under face 19 of the cam Pstrikes the upper edge of arm 0, tilting the bell-crank and withdrawingarm 0 from the notch Z, immediately after which the pawl engages theratchet, and the section carrying the mold which has just been in usebegins to move from left to right. A slight further movement of theshaft causes the cam to clear the arm 0 of the bell-crank, and the arm 0under the action of the spring 0 springs forward again toward thesection which it has just released; but the notch has passed somedistance to the right and the arm 0 rests successively against the endof said section and against the end of the next adjacent section untilthe shaft has reached its extreme movement to the right, when, as beforedescribed, the last-named section has reached such a position relativelyto the arm 0 that the latter drops into the notch, as before described,and holds the section rigid during the nextsucceeding pressingoperation.

In order that the female die may be held Vertically rigid during thepressing operation, a table T is placed beneath the press so that wheel,a rod adapted to slide in bearings to which said pawl is attached, anarm adapted to engage each of said sections successively and hold themrigid, a cam on said rod in alinement with said arm, and mechanismconnecting the plunger-die with the rod.

2. In a glass-press, the combination with a plunger-die, of an endlessseries of pivoted sections, said sections constituting the moldsupports,pulleys around which said series of sections extends, a ratchet-wheel onone of said pulleys, a pawl coactin g with said ratchetwheel, andmechanism for moving said pawl into engagement with said ratchet wherebythe pulley is turned to withdraw one mold from beneath the plunger andsubstitute anits supporting-surface rests immediately beneath theplunger and so close to the sections that the latter will slide over thetable as they advance.

Beneath the'wheel K is a chute R, beneath which is a traveling conveyerS, leading to the annealing-oven. As the sections pass over the wheel Kthe article which has been previously pressed drops from the mold ontothe chute, whence it drops onto the conveyer, which transfers thearticle to the annealing-oven.

Having now fully described my invention, what I claim, and desire toprotect by Letters Patent, is.-

1. In a glass-press, the combination with a plunger-die, of an endlessseries of pivoted sections, said sections constituting the moldsupports,pulleys around which said series of sections extends, a ratchet-wheel onone of said pulleys, a pawl coacting with said ratchetother mold tor theone withdrawn and upset a mold.

3. In a glass-press, the combination with a plunger-die, of an endlessseries of pivoted sections, said sections constituting the moldsupports,pulleys around which said series of sections extends, a ratchet-wheel onone of said pulleys, a pawl coacting with said ratchetwheel, an armadapted to engage each of said sections successively and hold themrigid, and mechanism for successively withdrawing said arm out ofengagement with the section and for moving said pawl into engagementwith the ratchet.
